You can buy gluten free oats from most health food stores or online. Oats are naturally gluten free, however most oats in Australia are processed on the same lines as barley and so contain gluten. Gluten free oats have been processed in a dedicated gluten free production facility.
Smoothies are often not the most nutritionally balanced drink. They are often high in fruit sugars and protein, but will lack fibre and healthy fats. Which means you are left hungry about an hour after drinking one for breakfast! To make sure your smoothie fills you up and is nutritionally balanced I recommend adding a tablespoon of oil, such as flaxseed oil. As well as adding an element of fibre, such as chia seeds.
